“I would definitely recommend McCarthy’s One Hour Heating and Air Conditioning! They were so quick to get out to help us. I booked online on a Friday morning and they were here a couple of hours later. Sam was very knowledgeable and made sure to explain everything and answer our questions.”

“We had another service come out that clearly wanted to just sell us a new system. Then we called Macarthy. Not only did they report one of the potential problems to not be a problem, but they also found the real problem. Instead of just reporting it as a potential fix, he fixed it first to make sure the unit would function with the cheaper fix. I’m very impressed with the knowledge and ability!”

“I can’t say enough great things about McCarthy 1 Hour Heating and Air and especially their technician, BioZa! From the moment he arrived, BioZa impressed us with his incredible knowledge and professionalism. He was not only super informative but also worked incredibly fast — our issue was completely fixed within just 15 minutes of him being here. What truly sets BioZa apart is how he took the time to explain everything clearly, giving us valuable advice on what to watch for in the future and helping us understand when it might be time to consider a new air conditioner. It’s rare to find someone who is both highly skilled and genuinely cares about educating the customer. If you want quick, reliable, and expert service with a technician who goes above and beyond, look no further than McCarthy 1 Hour Heating and Air. BioZa’s work deserves an A++ rating — absolutely outstanding! Thank you so much for making this process easy and stress-free. We’ll definitely be calling you again!”
